This is a terrible situation for the woman and her family, but there's clearly some missing and/or inconsistent info in this story. Neither Swedes nor UK citizens require a visa to enter the UAE. So bad visa, new visa, all that is strange. The one glass of wine thing is a red herring, but filming (and causing a scene) was probably a bad idea (it's not allowed at passport/border control in many countries, actually. Just try that at US immigration and see what happens).
